TRANSMISSION OR BRAKE BAND.

Application filed November This invention relates to transmission and brake bands for Ford motor vehicles and seeks, among other objects, to provide a band which may be readily removed by the'owner of the car as, for instance, when on the road, and wherein the band will embody an easily removable lining so that after the band has been taken out, a new lining may be readily substituted for a worn lining and the band replaced in the vehicle transmission.

A further object of the invention is to provide a band wherein the ear irons thereof will both be removable so that the band may be withdrawn from the transmission case by either end thereof, as found most convenient, after removing the proper ear iron.

Another object of the invention is to provide a band wherein the ear irons will both be formed to lock the removable lining in position upon the band.

And the invention seeks, as a still further object, to provide a band wherein, at one end of the band, the resilient strap thereof will be provided with a stop lug to cooperate with the ear iron at the adjacent end of the strap for limiting the lining against endwise displacement at said end of the band.

Other objects of the invention not specifically mentioned in the foregoing, will ap pear in the course of the following description.

In the accompanying drawings:

Figure 1 is a perspective view of the improved band.

Figure 3 is a detail sectiona-lview through ,the other end of the band.

Figure t is a detail elevation of the end of the band shown in Figure 2.

Figure 5 is an elevation of the end of the band shown in Figure 3.

Figure 6 is a transverse sectional view on the line 66 of Figure 1, looking in the r direction indicated by the arrows.

Figure is a fragmentary longitudinal sectional view showinga slightly different embodiment ofthe invention. y

In carrying the invention into effect, I employ a resilient metallic strap 10 of suitable width, and formed from the material 30, 1925. Serial N0. 72,265.

of the strap, is a medial channel 11 extending from end to end of the strap. At each end thereof, the strap is provided, as particularly seen in Figures 2 and 3 of the drawings, with a pair of longitudinally spaced outstanding headed anchoring studs 12, and removably engaged with said pairs of studs are ear irons l3 and 14: in which are formed keyhole'slots 15 accommodating the studs. conform to the curvature of the strap 10 and, at their outer ends, are each provided with a pair of spaced upstanding ears 16 to accommodate the usual operating shaft of a Ford transmission. Formed on the outer and of the ear iron 18 is a pair of transversely spaced depending terminal lugs 17- overhanging one end edge of the strap 10 to abut thereagainst, and formed on the outer end of the ear iron 14 is a similar pair of depending terminal lugs 18 overhanging the other end edge of said strap to abut thereagainst. These pairs of lugs will thus cooperate with the end edges of the strap for locking the ear irons against longitudinal movement away from the ends of the strap to become disengaged from the anchoring studs 12. However, either ear iron may be removed by flexing the adjacent end of .the strap downwardly until said end of the strap clears the lugs of said ear iron, when the ear iron may be shifted away from said end of the strap and disengaged from its ancl'ioring studs in a manner which Will be well understood; As shown in Figure l, the ear irons are grooved. at their lower sides to snugly fit over the channel 11 of the strap and rest fiat against the ends of the strap. Overlying the inner face of the strap 10 is a removable lining including a resilient metallic backing strip 19 of a width equal to that of the strap, and extending from end to end of said strip at its inner side is a suitable friction facing 20 secured to the strip by a series of longitudinally spaced rivets 21. As brought out in Figure (5, the heads of these rivets are freely accommodated in the channel 11 of the strap, and formed on the side edges of the strip, at suitably spaced points, are pairs of angular oppositely disposed lugs 22 embracing These ear irons are curved to the side edges of the strap for slidably connecting the backing strip thereto. At the same time, these lugs will also serve to hold the backing strip against lateral displacement from the band and attention is now particularly directed to the fact that, as shown in Figures 4. and 5 of the drawings, the pairs of lugs 17 and 18 of the ear irons are of a length to overlie the end edges of the backing strip so that in addition to their function of locking the ear irons against longitudinal movement away from the ends of the strap 10, as previously pointed out, said lugs also serve to lock the backing, strip 19 with its facing 20 against endwise displacement froin the strap. Formed on the left hand end of the strap 10, as seen in Figure 1, is a terminal downturned lug 23 which lies between the lugs 17 of the ear iron 13 and overlies the adjacent ,end edge of the backing strip 19 to cooperate with said lugs for additionally locking the backing strip against endwise displacement at said end of the strap so that endwise thrust on the backing strip and its facing, set up by-the rotation of the clutch drum about which the transmission band is engaged, cannotserve to displace the lining.

As will now be seen in view of the foregoing, my improved band may be removed from the transmission case of a Ford vehicle by removing the ear iron 13, for instance, at one end of the band, when the other end of the band may be grasped and the band pulled endwise from about the coacting drum of the transmission. However, if found more convenient, the ear iron 14 may be removed and the band pulled from the transmission case by grasping the ear iron 13. After the transmission band has been so removed and the ear iron 14 has been displaced from the adjacent end of the strap 10, the backing strip 19 may be shifted longitudinally on the strap toward said end thereof and thus disengaged from said strap, when, of course, a new lining may be readily substituted for the worn lining. This accomplished, the band may be again installed in the transmission of the vehicle by sliding the band endwise about the proper drum of the transmission, when one or both of the ear irons, as the case may be, may be again applied to the band so that the band may function in the customary manner. Thus, as will be seen, I provide atransmission band which will eliminate the necessity of going to a repair shop in order to have the lining of the band renewed.

In Figure 7 of the drawings, I have shown a slightly different embodiment of the invention wherein the strap 10 is provided near its ends with pairs of spaced hooks 24: which are preferably struck from the strap, and these hooks are formedt-o engage in the slots 15 of the ear irons, the ear iron 14 being shown. The hooks thus serve the purpose of the studs 12 of the construction first described. Otherwise, this modified structure is identical with the prior embodiment of the invention and further description is accordingly believed unneces sary.

Having thus described the invention, what. I claim is:

1. In a transmission band, the combination of a strap, a removable lining carried thereby and slidably removable from the strap, and freely detachable ear irons connectedv with .the ends of the strap and provided with spaced forwardly. and inwardly projecting lugs to overlie and abut the ends of the lining, for locking the lining against endwise displacement.

2. In a transmission band, the combination of a strap, a removable lining carried thereby and slidably removable from the strap, freely detachable ear irons connected with the ends of the strap and provided with means to coact with said lining for locking the lining against endwise displacement, and auxiliary locking means carried by the strap at one end thereof to ,coact with one end of the lining for limiting the lining against displacement at said end of the strap.

3. In a transmission band, the combination of a strap, a removable lining carried thereby and slidably removable from the strap, freely detachable ear irons connected with the ends of the strap and provided with. lugs to overlie the ends of the lining for locking the lining against endwise displacement, and an auxiliary lug carried by the strap at one end thereof to overlie the adjacent end of the lining for limiting the lining against displacement at said end of the strap.

4. In a transmission band, the combination of a strap, freely detachable ear irons carried by the ends of the strap and shiftable longitudinally away from the ends of the strap for detaching said irons from the strap, said ear irons being provided with spaced forwardly and inwardly projecting lugs to overlie and abut the end edges of the strap for normally locking said ear irons against longitudinal movement away from the ends of the strap, and a lining slidably connected with the strap and shift able longitudinally thereon to be removed from the strap, the lugs of said ear irons overlying the ends of said lining for normally locking the lining against displacement.

5. In a transmission band, the combination of a strap, freely detachable ear irons carried by the ends of the strap and shiftable longitudinally away from the ends of the strap for detaching said irons from the strap, said ear irons being provided with lugs to overlie the ends of the strap for normally locking said ear irons against longitudinal movement away from the ends of the strap, a lining slidably connected with the strap and shiftable longitudinally thereon to be removed from the strap, the lugs of said ear irons overlying the ends of said lining for normally locking the lining against displacement, and an auxiliary lug 10 formed on the strap at one end thereof to overlie the adjacent end of the lining for additionally locking said lining against displacement at said end of the strap.

In testimony whereof I aflix my signature.
